Lindsay Lohan has been ordered to appear in a Beverly Hills court on Friday for a progress report in her two DUI cases, a court spokeswoman confirms.

Actress Lindsay Lohan has been ordered to appear in court on Friday following media reports that she may have violated the terms of an alcohol education program imposed for a 2007 drunk driving case.

Lohan, 23, risks being sent to jail if she is found to have broken her probation or other orders imposed as part of her sentence.

Beverly Hills Superior Court judge Marsha Revel told Lohan to attend Friday's normally routine hearing in person, court officials said.
